I recently lowered my 350Z with Tein Basic coilovers and added SPC camber kits for front and rear with toe bolts. Put new rear tires (285/30/20) and they didn't last for more than 4months. Inner Wear.
THe tech adjusted in factory specs..

Am I missing something here??

 

Time is meaningless, how many miles did you put on them?

My guess is that they aren't really aligned to spec. What "tech"?

 

Post your alignment specs

 

No photos. No comment.

 

Got them done at a regular alginment shop who stated they've dealt with lowered cars already...
The car is my daily driver and I put about 30miles a day.

Anything that can help?

 

the problem is the shop will ahve a list of what your car is supposed to be at, and camber is supposed to be negative, and theres supposed to be some toe.. but you dont want that, but You dont want factory spec anymore.. try to get them to zero it out as much as possible. I think i have like -1 degree rear camber and zero toe.
TOE is whats killing your tire inside edges tho ..

 

glad i stumbled upon this... quick question(dont mean to hijack) but i thought neg/pos camber was bad? even with lowered cars

 

OP Post your alignment sheet specs. Thats the easiest way we can help you.

 

Factory - within spec has negative camber. this will wear the crap out of the inside edges.

You want to adjust your camber as close to 0 as possible and set your toe correctly.

When I first bought my Z at 25k miles the tires were almost to the cords on the inside edges. I slapped on a new set and adjusted the camber as close to 0 as possible with factory parts and set the toe, 10k miles later no inside wear.

good luck

 

Alignment issues.

 

Factory specs call for negative camber because it increases vehicle stability and improves handling. Setting the camber to 0 will cause poorer handling at slow speeds (handling will increase at speed due to suspension compression caused by downforce, which adds negative camber). Same thing with toe, it should be 0 at highway speeds, not at a stand still.


To the OP, no one can help you without pics and/or spec sheets.
